In a large skillet, gently warm EVOO. Add onions and sauté 5 minutes. Add garlic and sauté another minute or two. Then add remaining ingredients except lemon juice. Use liquid from beans in can, otherwise, add ½ cup water. Mix everything well, cover pot and simmer dish for 20-30 minutes. Turn off heat, add lemon, taste and adjust for seasoning. Serve garnished with any number of things. Some that I like are crumbled Mt. Vikos feta cheese, pine nuts, shelled pistachios (which we have too, of course), steamed shrimp, Wolfe Neck Farms meatballs or Pecorino Romano.
*or two cups cooked beans with ½ cup liquid.
